Printable worksheet for practicing metric unit conversions, featuring 10 pairs of conversion exercises.

Measuring Units Worksheet: Conversion Problems

The worksheet involves converting between different units of length in the metric system. The key relationships to remember are:

- 1 kilometer (km) = 1,000 meters (m)
- 1 meter (m) = 100 centimeters (cm)
- 1 centimeter (cm) = 10 millimeters (mm)

Using these relationships, we can solve each problem step by step.
